I now have four of the best quality grinders on the market. Without telling you all the brands I wanted this grinder because of the quality put into Hitachi products. This is a very well made 4 1/2 inch grinder with a heavy duty rating & great quality. The grinder is a few onces heaver but that is why it's more heavy duty. I placed a 3/4" diamond blade in this grinder and had no problem removing concrete & mortar in one pass between the brick joints. None of my other grinders could handle the size or load this grinder can handle. Hitachi puts out fantastic quality tools for pros and homeowners. If you need this type of tool don't waste your money on a cheap grinder, this one will put the others to shame.

We use this grider to trim the hoofs on our dairy cattle. It is the only one that has lasted more than 1 yr. We are on our 3rd one now. A little on the heavy side, but the durability is worth the extra weight. Until we found this grinder, we were going through different one every week to a month. I've bought 3 and I'll buy more.

Price is little steep @ $90 but is well worth it!

Paddle switch is very well designed it locks on easily one-handed ( I tried dewalt's and it did not work nearly as well)

Seems a little heavy @ first but is really easy to handle

Wish they included a case though

Works well with sanding kit

Hitachi seems to specialize in delivering above-average tools at below-average prices. This grinder is powerful, fast, and durable. The toolless guard helps a ton, and can be used as a fence in a pinch (used a diamond wheel and straight edge to cut tile-- worked perfectly!).

There's no a whole lot to say about a grinder, other than lighter is better. This grinder isn't super-light, but not unmanageably heavy. 9 Amps is about all you'll ever need in a small grinder.

I'm not sure I like the paddle switch. I think I'd prefer a trigger switch, which is hard to find on a small angle grinder (they generally either have paddle switches or the sliding switches). The paddle switch on this unit doesn't seem to cooperate all the time-- it will lock on when you don't want it to, and it will fail to lock on at other times. I admit this is probably operator error on my part, but I have struggled with it from time to time.

Overall, this is a capable grinder at a great price. I believe the Bosch and Makita units to be the cream of the class, but they cost a bunch more, too.

Our company uses and abuses 4 1/2 inch angle grinders, and this particular model by Hitachi is the toughest of the bunch. We own Makita, Bosch, Diteq and other brands, but this Hitachi has outlasted all of them under the same conditions. I would highly recommend this tool, as it is well designed and takes a lot of abuse without breaking. We do nothing but concrete grinding, and most of our grinders last less than a year, except for this one. We own 3 of them, as they've proven to be our #1 tool.

Only used it lightly a few times so far, but it is a solidly built tool and easily cut through corrugated metal roofing panels. Guard is easily re-positioned, and the trigger setup is nice once you get the hang of the locking mechanism. I've used it to sharpen garden tools and fix some other random things around the house as well. Very useful tool! I second the other reviewer who was surprised it does not come with a case. Hitachi should at least send a soft case or some method of transport with the tool. As a side note - I was out on a commercial construction jobsite recently and saw the structural steel guys had all Hitachi grinders of various sizes, including this one. I did not ask about them, but those guys would not bring along tools that don't work, I do know that much.

I have been using this grinder to remove the exterior paint of our apartment and so far so good. The machine was so powerful and I think it will last long. It is far better than my old milwaukee grinder.
